Treatment Results of Osteoplastic Frontal Sinus Operation / 대한이비인후과학회지

ABSTRACT

Objectives: We aimed to look for indications and find out treatment outcomes of osteoplastic frontal sinus operation (OFSO) for frontal sinus diseases. MATERIALS AND METHODS: We retrospectively evaluated nine patients undergoing OFSO between 1993 and 1997 and examined indications for surgery, complications, and outcomes. All patients were male and their ages ranged from 27 to 63 years with a mean age of 42 years. RESULTS: Indications for surgery were found in 3 cases of fracture involving frontal sinus, mucopyocele (3 cases), osteoma (2 cases), and inverted papilloma (1 case). In five patients, bilateral frontal sinuses were opened through bone flaps and in four patients unilateral frontal sinus was opened. Follow up information was available on 8 patients all of whom were cured without evidence of recurrence to date. No serious complications, either intracranial or orbital, occurred, however, all 8 followed up patients have persistent abnormal forehead sensation and abnormal bony contour of forehead, either depression or bossing, developed in 4 patients. CONCLUSION: Osteoplastic frontal sinus operation seems to be a rational approach to eradicate frontal sinus diseases such as tumors, fractures, and mucopyoceles, which cannot be treated by endoscopic sinus surgery. Minor sequelae such as supraorbital hypesthesia and forehead deformity may develop postopera-tively and the patients should be informed of them preoperatively.
